About
Intelligent Posting Schedule
Provide data-driven posting time recommendations and help schedule content for maximum first-hour engagement velocity.
Input
The user may ask:
- "When should I post this?"
- "Build me a weekly posting schedule"
- "What's the best time for [content type] aimed at [audience]?"
- Or provide content ready to schedule
Process
Step 1 — Load Timing Data
Read [../../../reference/timing.md](../../../reference/timing.md) for the complete timing reference.
Step 2 — Gather Context
Determine:
- Content type: Post, thread, poll, announcement, etc.
- Target audience: Developers, general tech, consumers, specific niche
- Author's timezone: For converting recommendations
- Posting history: Any known patterns or constraints
- Urgency: Time-sensitive content vs. evergreen
Step 3 — Generate Recommendation
For a single post:
- Recommend the top 3 posting windows with rationale
- Account for content type × timing matrix
- Consider the day of week
- Note: "Be available to reply for 30-60 min after posting" for every recommendation
For a weekly schedule: Build a 5-day plan:
Monday: [Content type] at [time] — [rationale]
Tuesday: [Content type] at [time] — [rationale]
Wednesday: [Content type] at [time] — [rationale] ← peak day
Thursday: [Content type] at [time] — [rationale]
Friday: [Content type] at [time] — [rationale] (lighter content)
- 3-5 posts per week for quality-focused accounts
- Space posts minimum 2 hours apart on multi-post days
- Threads on Tuesday-Thursday mornings (highest dwell time)
- Lighter content (polls, questions) on Monday/Friday
For a content calendar: Build a 2-4 week plan mixing:
- 1-2 threads per week (highest engagement format)
- 2-3 single posts per week (insights, tips, observations)
- 1 poll per week (engagement boost)
- Daily reply/engagement time (15-30 min)
Step 4 — MCP Integration
If OpenTweet MCP is available:
- Offer to schedule content directly
- Use
opentweet_batch_schedulefor weekly plans - Suggest adding high-performers to the evergreen queue
Step 5 — Output
Present:
- Recommendation with specific times (converted to user's timezone)
- Rationale for each slot
- Engagement reminders (reply windows, availability needed)
- Content type suggestions for each slot if doing a weekly plan
Key Rules
- Always specify timezone
- Wednesday is the peak day — schedule best content here
- Avoid weekends unless the audience is consumer/hobby
- Never schedule without a reply plan — posting and disappearing wastes the first-hour window
- If user can't be available to reply, schedule for the next available window where they can be present
